WAsP is a Windows program for predicting wind climates and wind resources and estimating power production from wind turbines and wind farms. It was developed by the Wind Energy Division at Risø DTU in Denmark.
A wtg file is an XML-format data file containing one or more sets of power and thrust curves that characterise a wind turbine generator.
Use WAsP on Microsoft Windows to work with a wtg file. The file can also be viewed as XML in a text or XML editor, but WAsP is required to use the turbine data in wind-resource and power-production calculations.
Conversion to other formats is not possible.
